Bebe Rexha and Jordan McGraw (the son of TV personality Dr. Phil McGraw) will open.

On Tuesday, Fiserv Forum stirred up speculation by posting a cryptic "Happiness Begins Here" message on its social media channels, with the date, "Tuesday, Sept. 17."

The Jonas Brothers' forthcoming album is called "Happiness Begins" (out June 7), and the band and concert promoter Live Nation started posting their own cryptic "Happiness Begins" messaging on social media Tuesday.

The tour is great news to longtime heartbroken Jonas Brothers fans in Milwaukee. The band was set to play the Riverside Theater in 2013 when it abruptly canceled its tour a couple weeks before the show and announced its indefinite hiatus.
